DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 to 11 thereof, a new and improved snow melting heater mat apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The FIGS. 1 and 2 illustrate a prior art heated mat structure, as set forth in the U.S. Pat. No. 4,967,057, illustrating the utilization of a plurality of interconnected mat members whose mat are of a flexible solid configuration.
More specifically, the now melting heater mat apparatus 10 of the instant invention essentially comprises a plurality of rigid heating mats 12 positioned in electrical communication relative to one another positioned adjacent an associated vehicle 11, with the heating mats in electrical communication to an electrical power supply 13 directing electrical energy to the heating mats 12. The heating mats 12 are formed as a rigid housing, including a top wall 14 spaced from a bottom wall 15, with a continuous side wall 16. A plurality of serpentine resistance heating members 17 are directed throughout the heating mats 12 between the top wall and the bottom wall 14 and 15 respectively. Flexible connector cables 18 are directed between adjacent side walls 16 of adjacent heating mats 12 to effect electrical communication of the heating members 17 of adjacent heating mats 12. The flexible connector cables 18 each includes a surrounding coil spring 19, with each end of the coil spring 19 mounted to adjacent side walls 16 of adjacent mats 12. The heating members 17 are mounted within insulator posts 20, in a manner as illustrated in FIG. 6. Further, a rheostat 21, as illustrated in FIG. 8, is selectively utilized to provide for energy selection and degree of heating within the associated mats 12.
The mats 12a set forth a modified mat construction of a cellular type configuration. The modified mats 12a, as illustrated in the FIG. 9 for example, includes orthogonally intersecting plural first and second wall members 22 and 23. The first wall members 22 are arranged parallel relative to one another intersecting orthogonally parallel second wall members 23 to form cellular openings 31 in a matrix configuration, in a manner as illustrated in the FIG. 9. The cellular openings 31 are directed between the top and bottom wall portions directed therethrough of the modified mats 12a. Further, the heat members 17 are directed along the top of each of the second wall members 22 and 23 in a serpentine configuration, as illustrated in FIG. 9.
The FIG. 11 illustrates the further use of a first magnetic mounting block 25 magnetically adhered to a ferrous metallic side wall 16a utilizing a tether cable 27 for securement to a second magnetic mounting block 26 for magnetic securement and positioning of the heating mats 12a relative to the vehicle door 24, as well as the vehicle body 11. The proper spacing is thereby afforded of the heating mats 12a in this manner. Further, a flexible securement web 28 is secured at a first end to the side wall 16, and at a second end to a rigid securement web tube 29 formed with a tubular cavity 29a coextensively therethrough to receive a signal flare cylinder 30 that may be utilized in matters of emergency to indicate danger or orientation of the vehicle in particularly deep snow falls.
It should be further noted, as illustrated in FIG. 11, that the rigid securement web tube 29 is arranged for reception within the vehicle 11 between the vehicle 11 body and the associated door 24 to discourage unauthorized removal of the apparatus relative to the vehicle 11 during use.
As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
